Wow it is covered in there with major dirt and tar/nicotine!
I'd clean that chassis thoroughly before powering it up. If it's covered with cigarette tar and nicotine, not to mention ordinary dirt and dust, it could create a fire hazard. Frankly, I'm amazed it didn't catch fire long before you got it, as filthy as you say the chassis is.
